The EIA assigns each manufacturer a three-digit code (there are some with one, two or four digits).When dating an instrument by the ‘pot code,’ keep two things in mind: The potentiometers must be original to the piece (new solder, or a date code that is off by ten or more years is a good giveaway to spot replacement pots); and the pot code only indicates when the potentiometer was manufactured!53 850020 from 1972 |Source=[ |Date=June 17, 2006 |Au This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. When looking up the age of your instrument, complete the following steps: (1.) Find your instruments catalog page and year that the catalog was made. White kept very detailed records but when the company was sold to the Seeburg Corporation all official records were destroyed.If the pot is an original, it indicates a date before which the guitar could not have been built – so it’s always a good idea to have extra reference material around.Finally, a word of caution: This method applies only to American made pots and not all potentiometer manufacturers subscribed to the EIA source code date.
If you have catalogs, ads or pictures of guitars that can help fill in some of the blanks, please let me know (Michael Wright, PO Box 60207, Philadelphia, PA 19102).
tons of places have them on their websites but none actually have them... I found ONE, a prototype made for Gibson's dealer in the UK (Rosetti) at the launch of the line which, after telling the seller in Glasgow that they had no more and couldn't get more, remembered they had stashed away in the warehouse? I scoured Sweden, Denmark, France, Germany, Italy...
I got a great price, a decent Stagg tweed Les Paul case thrown in.
If the code does not fit the above criteria, don’t force it and skew your dating results.
While most think of the history of American guitars in terms of American manufacturers, if you’ve followed this column you know the tradition is much richer.
